FLUsHlNe-VALV'E.

SPECIFICATION forming' part of Letters Patent N o.. 694,107, datedFebruary 25, 1902.

Application filed May 13, 1901.

To all whom, it may concern,.- A

Be it known that I, FREDERICK WILLIA MEYER, of Louisville, in the countyof Jefferson and State of Kentucky, have invented certain new and usefulImprovements in Flushing-Valves; and I herebydeclare that the followingis a full, clear, and exact description thereof, reference being had tothe accom panying drawings, which form part of this specification. l

This invention is a flushing-val ve for sinks, water-closets, ttc., andis an improvement upon the valve shown in Patent No. 661,885, granted tome November 13, 1900; and the object of my present inventionis toprovide a valve which will flush the closet, sink, te., at a desiredpressure of water and will automatically regulate itself, so that itwill not flush under higher pressures, but willrst reduce the pressureand then cause the flushing, vas hereinafter more fully explained.

The invention therefore consists in the l novel construction andcombinations of parts, as set forth in the several claims herein, andthe accompanying drawings illustrate the invention as applied to aWater-closet.

Figure l is a side view of the valve applied to a Water-closet bowl,showing the operative connection between seat and valve, Fig. 2 being anenlarged section through the com plete valve. i

The valve-casing is roughly of U shape, having an inlet-chamber A and anoutletchamber B, connected by the flushing-chamber C.v The inlet-chamberA communicates with the service-pipe A at opening a and with the lowerend of chamber C, but communication between chambers A and C beingcontrolled or closed by a valve D, and communication between chambers Band C may loe closed by valve E on a stem F, extending through chamberB, as shown, and projecting into the closet-bowl XV. The casing isprovided with suitable seats d e for valves D E, respectively, as shown,and said valves open in opposite directions and are arrangedsubstantially as in my said patent, so that when one is open the othershould be closed.

lFor this purpose the valve D is attached to an arm f, attached to theinner end of rod F within chamber C, substantially as shown in my saidpatent. To obtain an automatic Serial No. 60.075. (No model\ regulationof the liushing pressure, however, the valve E is not rigidly connectedto stem F, but is of peculiar construction and controlled by a springwhich can be adjusted so as to unseat the valveE at a predeterminedpressure after valve D is' closed.

For thisv purpose the valve E is composed of a sleeve i E', looselymounted on stem F and having a disk E2 attached to its inner end, andpreferflow when headf is separated from the sleeve ,Y

by the inward movement of valve-stem F.

The chamber C has an outlet c above valve E,which communicates with aflushing or storing tank or reservoir (not shown) through a pipe C', asusual.

The inner end F2 of stein F is guided in a hole 7L in a screw-cap H,closing an opening in the casing directly opposite seat e and throughwhich access can be had to valve E. The outer end of chamber A is closedby a similar screw-cap I, by removing which access can be had to valveD. These screwcaps facilitate assembling of parts and cleansing ofthecasing.

Stem F projects into the closet-bowl and through an opening in theiiushing-rim w therein, the inner end ofA springK having a bearingagainst this rim w, a washer K' being interposed between the spring andflushing-rim to prevent water splashing through the opening of the rim.The inner end of rod F is hinged to the lower end of an oscillatinglever L, fulcrumed on a stud tu', attached to the rim w, the upper endof this lever L carrying a friction-roller l, which is adapted to engagea cam m on the seat or set-hinge M, as indicated in the drawings. SpringK is powerful enough to normally hold the seat slightly raised and valveD closed; but when pressure is exerted on the seat, as in use, lever Lis rocked, forcing rod F inward, opening valve D and closing valve E.Thereupon water ICO fiows through chambers A Cinto the liushing orstorage tank (not shown) and accumulates therein under more or lesspressure. Now when the seat is released the stem F is shifted inwardlyby spring K, so as to close valveD and tension-spring G, which willexert itself to open valve E; but if the pressure of water in chamber Cis such that spring G cannot overcome it the pressure is graduallyreduced by the water escaping from chamber C into chamber B through thesmall passages in the sleeve E', as shown, these passages beingordinarily closed by the head f of an arm f; but when siem Fis initiallymoved back this head f is moved slightly away from thesleeve, allowingwater to pass between the head f and disk to passage E5, and the watercontinues to escape through these passages until the pressure in chamberC is reduced suiiciently to enable spring G to unseat valve E, which itthen does quickly, and the Water rushes out through chamber B, flushingthe closet thoroughly. The spring G may be adjusted so as to elfect theunseating of valve E only at or below a certain pressure, and then ifthe pressure in chamber C is above the desired flushing-pressure valve Ewill not be opened until the pressure is reduced to the desired point.When rod F is again actuated so as to unseat valve D,it simultaneouslypositively closes valve E, so water will accumulate in the fiushing-tankas is desired.

Having thus described my invention, what I therefore claim as new, anddesire toseeure by Letters Patent thereon, is-

1. The combination in a valve, of the casing, the chambers therein, thevalve-stem,.the valve loosely mounted on said stem having minutewater-passages therethrough, a head adjustably connected to the stemadapted to seat the valve and close the passages when the stem is movedin one direction, and a spring on said stem at the opposite side of thevalve interposed between a collar on the stem and the valve, and adaptedto unseat the' valve when the stem is moved inwardly and the waterfpressure is suitably reduced all constructed and adapted to operatesubstantially as described.

2. In a valve, the combination of the casing having outlet and ilushingchambers, a valve forclosing comm unication between said cham bers, anda stem supporting said valve, said valve comprising asleeve looselymounted on the stem, and having longitudinal water-passages extendingthrough the valve; and a washer and disk on the sleeve; with a head onthe stem adapted to forcibly seat the valve and close the said passageswhen the stem is moved outward, and a spring for unseating the valvewhen the pressure is suf'icientl y reduced, all constructed and adaptedto operate substantially as and for the purpose described.

3. In a valve, the combination of the casing having outlet and flushingchambers, a valve through the valve; with a head on the stem4 adapted toforcibly seat the valve and close the said passages whenthe stem ismoved outward, and a spring interposed between a collar on said stem andsaid valve, and adapted to unseat the valve when the pressure issufficiently reduced, all constructed and arranged to operatesubstantially as and for the purpose described.

4. In a valve, the combination ot the inlet, outlet, and fiushingchambers, the oppositelydisposed valves closing communication betweenthe storing-chamber and inlet and outlet chambers respectively, avalve-stem upon which the outlet-valve is slidingly mounted, and towhich the inlet-valve is rigidly conneeted, and passages for escape ofwater past the outlet-valve; with means for operating said stem to openor close the inlet-valve, and to close the outlet-valve when inlet-valveis opened, and a spring adapted to unseat the outlet-valve at or below acertain pressure in the storage chamber, when the said inletvalve isclosed, substantially as described.

5. In a valve, the combination of the inlet, outlet and flushingchambers, the oppositelydisposed valves closing communication .betweensaid storing-chamberand inlet and outlet chambers respectively, avalve-stem upon which the outlet-valve is slidingly mounted, and towhich the inlet-valve is rigidly connected, said outlet-valve havingpassages for escape of water therepast before it is unseated; wit-hmeans for operating said stem to open or close the inlet-valve, and toclose the outlet-valve when the inlet-valve is open, and a spring onsaid stem adapted to unseat the outlet-valve at or below a certainpressure in the storage-chamber after the said inlet-valve is closed,substantially as and for the purpose set forth.

In testimony that I claim the foregoing as myown I affix my signature inpresence of two witnesses. l
